Since my last we have had every day more or less firing on the Charlestown side, but without much damage on either part. We have been very quiet all night, and have had little disturbance through the day, till last Friday, when the following battle royal in the streets drew all our attention, and has since engrossed all our conversation. ー Mr. [Benjamin] Hallowell, a Commissioner of the Customs, had written four letters to Admiral [Samuel] Greaves. The subject of these letters was, it is said, an expostulation with the Admiral for taking forcibly, for his own use, one half of a quantity of hay, purchased by the Commission on some of the islands, for allowing the other half to pass. The Commissioner meeting the Admiral in Milk-street, who had never thought proper to answer any of his letters, stopped and enquired, why that notice had not been taken of his letters, which he, as a Gentleman, had a right to expect? To this civil question, the Admiral replied in his usual style; and while the Commissioner was whispering a challenge to him, returned a blow in the face. Though Mr. Hallowell was unarmed, the Admiral had recourse to his sword, on which the former rushed upon him, forced it from him, broke it over his knee, and then flung it in Greaves's face; after this they went to it with their fists, but were soon parted. ー The Admiral has come off with a black eye. He has not yet proposed a renewal of battle, probably preserving himself for the Yankies, who have already carried off all his fresh stock, burnt his hay on the islands, and destroyed the light-house twice under his very nose. One of his relations, w,ho expects the first vacant ship, challenged the Commissioner, who replied, he knew no such person as the challenger, but should always defend himself whenever he should be attacked.---- In his own department, the Admiral is more hated and despised, if possible, than he is by the army and the rebels. Capt. M---- is waiting to accompany him to England, whenever he shall be recalled; and if the Admiral can rally his spirits, their interview will not end with a boxing match.
